Mapping with confidence; delineating seagrass habitats using Unoccupied Aerial Systems (UAS)

Remote Sensing in Ecology and Conservation, 2019
There is growing interest in the use of Unoccupied Aerial Systems (UAS) for mapping and monitoring of seagrass habitats. UAS provide flexibility with timing of imagery capture, are relatively inexpensive, and obtain very high spatial resolution imagery ...

Blue Carbon Storage in a Northern Temperate Estuary Subject to Habitat Loss and Chronic Habitat Disturbance: Cowichan Estuary, British Columbia, Canada

Frontiers in Marine Science, 2022
Vegetated coastal ecosystems can contribute greatly to long-term carbon sequestration and greenhouse gas emission mitigation, providing a strong argument for their protection and restoration.

An autonomous and economical benthic incubation chamber for measuring dissolved oxygen fluxes in shallow, low‐flow environments

Limnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract Benthic incubation chambers enclose a known volume of water overlying a known area to measure water chemistry changes and are typically used to quantify the metabolic activity of benthic organisms or communities. Here we present an economical benthic incubation chamber for shallow, low‐flow environments, built using off‐the‐shelf components ...

Spatial and Temporal Variation of C, N, and S Stable Isotopes and Seagrass Coverage Related to Eutrophication Stress in Zostera marina

Coasts
Zostera marina is an ecologically valuable species that has been declining due to anthropogenic environmental stressors. In this study, spatial and temporal indicators of eelgrass stress, such as coverage and biomass, were compared with the isotopic ...

Establishing a Baseline for Regional Scale Monitoring of Eelgrass (Zostera marina) Habitat on the Lower Alaska Peninsula

Remote Sensing, 2014
Seagrass meadows, one of the world’s most widespread and productive ecosystems, provide a wide range of services with real economic value. Worldwide declines in the distribution and abundance of seagrasses and increased threats to coastal ecosystems from

Time tells: plasticity and developmental asynchrony underlie trait variation in a dune‐building grass

Oikos, Volume 2026, Issue 5, May 2026.
Habitat‐modifying plants engineer landscapes through plant‐environment feedbacks. The strength of these feedbacks is determined by above‐ and below‐ground traits shaping landscape morphology. Besides interspecific differences, recent findings highlight that intraspecific trait variation, such as shoot density, can also influence landscape morphology ...

Rocking the Boat: Damage to Eelgrass by Swinging Boat Moorings [PDF]

Frontiers in Plant Science, 2017
Seagrass meadows commonly reside in shallow sheltered embayments typical of the locations that provide an attractive option for mooring boats. Given the potential for boat moorings to result in disturbance to the seabed due to repeated physical impact, these moorings may present a significant threat to seagrass meadows.

Low Climate Benefit of Nordic Coastal Marshes: Site Conditions Outweigh Grazing Effects and Shape Trade‐Offs Between Carbon Storage and Its Stability

Global Change Biology, Volume 32, Issue 5, May 2026.
Conceptual diagram of soil carbon cycling across climatic and environmental gradients in Nordic marshes and grazing effect. Denmark's warmer climate, high nutrient inputs, elevated salinity, and sandy soils promote rapid microbial decomposition of predominantly labile and root‐derived OC, driving high CO2 emissions and relatively high although unstable

Microbiome succession during ammonification in eelgrass bed sediments [PDF]

PeerJ, 2017
Background Eelgrass (Zostera marina) is a marine angiosperm and foundation species that plays an important ecological role in primary production, food web support, and elemental cycling in coastal ecosystems.

First Report of Marinomyxa spp. (Rhizaria: Endomyxa: Phytomyxea) Infection in Seagrasses Halophila beccarii and Halophila decipiens: Supporting Evidence for a Long‐Standing Symbiosis

Plant Pathology, Volume 75, Issue 3, May–June 2026.
A survey of phytomyxid parasites in seagrasses of the genus Halophila reveals previously unrecognised diversity and a widespread presence of Marinomyxa within Halophila meadows, supporting a tight co‐evolutionary relationship between the two genera. ABSTRACT Marinomyxa is a genus of obligate intracellular parasitic protists known to infect tropical ...
